Loss-cone instability modulation due to a magnetohydrodynamic sausage mode oscillation in the solar corona
(2019)
Solar flares often involve the acceleration of particles to relativistic energies and the generation of high-intensity bursts of radio emission. In some cases, the radio bursts can show periodic or quasiperiodic intensity ...
Near-octave-spanning breathing soliton crystal in an AlN microresonator
(2021)
The soliton crystal (SC) was recently discovered as an
extraordinary Kerr soliton state with regularly distributed
soliton pulses and enhanced comb line power spaced by
multiples of the cavity free spectral ranges (FSRs), ...
Surface studies of Fe3O4(001), Fe/Ge(001) and Fe3O4(001)/Ge(001)
(Trinity College (Dublin, Ireland). School of Physics, 2006)
This work consists of surface studies of three systems; firstly, the (001) surface of a Fe3 O4 single crystal, secondly, the initial nucleation of Fe on the Ge(001) surface, and finally, iron oxide formed on Ge(001). The ...
Strain-induced isosymmetric phase transition in BiFeO3
(American Physical Society, 2010)
We calculate the effect of epitaxial strain on the structure and properties of multiferroic bismuth ferrite, BiFeO3, using first-principles density-functional theory. We investigate epitaxial strain corresponding to an ...
Heat Transfer in Open Quantum Systems
(Trinity College Dublin. School of Physics. Discipline of Physics, 2023)
In most situations of practical interest, quantum systems are not isolated from their surroundings but are interacting with an environment. The importance of such situations has been highlighted, for example, in the fields ...
Optical limiting study of double wall carbon nanotube-Fullerene hybrids
(2010)
In order to merge complementary temporal and spatial nonlinear optical characteristics of Fullerene and carbon nanotubes, synthesis of double wall carbon nanotube?Fullerene hybrid was performed by covalently linking DWNT ...
Developments in surface magneto-optical Kerr effect setup for ultrahigh vacuum analysis of magnetic ultrathin films
(2005)
We describe a surface magneto-optical Kerr effect (SMOKE) setup designed to study the magnetic properties of ultrathin films in ultrahigh vacuum (UHV). As in earlier systems, a crossed-poles electromagnet is used, which ...
Ballistic vs diffusive low-frequency scaling in the XXZ and a locally perturbed XXZ chain
(2020)
We study the matrix elements of local operators in the eigenstates of the integrable XXZ chain and of the quantum-chaotic model obtained by locally perturbing the XXZ chain with a magnetic impurity. We show that, at ...
Characterization of single-mode laser and tunable laser array based on etched high order surface gratings
(Trinity College (Dublin, Ireland). School of Physics, 2015)
Wavelength tunable single-mode semiconductor lasers play an essential role in modern optical communication systems. They are also rapidly replacing fixed-wavelength light sources in dense wavelength-division-multiplexing ...
The Effect of Surfactant Choice and Concentration on the Dimensions and Yield of Liquid Phase Exfoliated Nanosheets
(2020)
Liquid-phase exfoliation has progressed in recent years to become a common method for production of 2D materials. During exfoliation, surfactants can be used to stabilize the nanosheets against reaggregation. Here, using ...
